Refinements seem to be too difficult/problematic to differentiate. The basis is to allow firepower advantage for linear tactics and close combat advantages for deeper formations.

With these basings a linear formation will have more figures firing than pike armed units and can fight double the number of enemy battalions on an equal basis. Platoon firing can be awarded some advantage too.

Each base must have an NCO/Officer figure which can be removed when the base suffers a 'Command hit.'

Each formation has a command base of an officer, a battalion flag and a musician.
Regimental command bases should have a colonel on a horse, regimental colour and national colour also. (single battalion regiments have only the regimental command., multiple battalion regiments have the command base 'with' a battalion.)

HORSE: Historical variations are chaotic. This is a compromise for sanity's sake.
A troop on a base 75mm by 60mm deep is 5 figures in one rank. A squadron is two troop bases with a command base of two figures : officer and ensign. Troops need an officer figure to allow for command hits.

GUNS : 45mm by depth as necessary. With one figure plus 1 for every gun represented in the battery.
